Root zone ph question.

I just read the spec for it and you can only use it up to two weeks of flowering so it won't be much use now unfortunately. Thanks for the help though mate

Oh snap I thought you could use it up to the last 2 weeks I must've read it wrong if it's saying that then yeah definetely don't use it I don't want you getting sick or something! I've never used it before just read about it the one time I had a hermie I ended up cutting it down instead of chancing it pollinating the rest of my girls. It was a runt so I didn't miss it all that much.

Thanks man. Well to be honest the system I'm using was pretty much a drip system. It's a wilma! I don't know if you're familiar with them?

I was thinking about trying to build an external top off reservoir and attaching it to the wilma tub so that it has an overall bigger reservoir size. What do you think?

No I've never seen one of those before that's a first for me. So that's basically four pots sitting on top of a res where you have the roots growin down into the res? I'm not a fan of having the roots constantly flooded they like air just as much as we do. If you're having problems and want to add a res I'd raise that whole system up and set it up on top of a 5 gallon bucket. You could then move the pump down into the 5 gallon bucket and then have it setup where you're previous res is now a dry root chamber and be providing the root system with a lot more fresh air. You'd have to drill a hole in the bottom of the old res so that the solution could drain down into the 5 gallon bucket which would be the new res. You'd also probably need a little longer drip lines to reach from what it looks like. My problem with systems like yours is that the roots like to breathe and unless you have really cold oxygen rich water you'll usually have problems. You could also build a drip tote system that'd hold a lot more plants for a fraction of the cost of that unit. You're growth rate would explode if you can make a chamber to hold the roots open in air and easily breathing instead of being submerged. Do you have a store like wal-mart or target over there in the uk? If I was in your position I'd go to one and pick up some plastic totes and make some drip totes for your next grow.
